LOOSE-LEAF BOOK.

Specification of Letters Patent.

Patented Nov. 2-3, 1909.

To all whom it may concern:

Be it known that I, LoUIs E. MARSH, citizen of the United States, residing in the city and county .of San Francisco and State of California, have'invented new and useful Improvements in Loose Leaf Books, of which the following is a specification.

This invention relates to a new and useful device known as a loose leaf, or detachable leaf :book.

The object of my invention is to enable a person to quickly remove and replace the leaves of a book, and atthe same time a locking device; is provided which will prevent the accidental removal of the said leaves.

To accomplish this purpose, each leaf has bound to it, or fastened to it, along one of its edges, a suitably sized wire or rod which will project at the top and bottom of the same. This projecting: wire or rod can be of one piece, or length, and project at each end a suitable distance, or it can be madein two small lengths, and each piece suitably bound to, or fastened to each end; or rather, what would be known as the top'and bottom of the leaf. This projecting wire or rod is intended to fit into a hole or suitable recess, which is in a part of a frame somade to receive any number of such leaves, as the occasion, purpose, and size of. the book may require.

My invention includes combinations of guts, and details of construction which will more fully explained by reference to th accompanying drawings, in which- Figure 1 is at perspective view of my de- Fig. 2 is;a side elevation and partial section.

In the drawings, 2 representsa piece of wire which for convenience, has its opposite ends so fashioned that they may more quickly enter the receptacles intended for them.

A shows a 1eaf,'which canbe made of any paper substance, wood, metal, glass, or any substance suitable for its particular uses. 2 shows a binding, for the purposeof holdin said wire firmly .to the edge of sald leaf, an

it may be of any substance which is'suitable' to make a firm and secure joint, so the pa e A and the wire or-rod 2 W111 be proper y fastened together.

3 shows how an index, letter or word, character or symbol, can be attached to or near the edge, for the purpose of reference, said indexing symbol being kptrin. sight by therelative'pos'ition ofzon'e leaf to another when they are in their respective positions in the frame or' holding device.

4 shows one end of the receivin or re? t aining fixture for the leaves, andt is -consists of a piece of metal or suitable substance bent at right angles, so that one end or part can be used to hang the fixture up on the Wall; and the other part is that part wherein holes, indentations or recesses are placed, sogs to receive one end of the wires afore sa1 7 represents the frame, or suitable pieoewhich connects together and'retains in their respective places, the top and the bottom ends of the device; and this connecting piece can be of any substance which the require ments of the particular use to which: it? is subjected may demand.

In 'thepresent structure, the lower or'base portion of the frame 4* has holes madefor the insertion of the lower ends of-the rods 2 which carry the leaves A, and this=part front edge turned backward beneath the main dportion, as plainly shown at 5, in Fag.

lower ends of the rods-2t The uppenpartet is here shown-with its horizontal ortion similarly perforated with holes, WhlCh are so disposed with relation to the holes in the lower part, that the rods 2 at the upper end of each-leaf may be inserted into a ole corres ondin'g with the one at the lower end; an as here shown the upper perforated portion is sufficiently shorter than the lower so that the leaves A will stand at such an angle that if the device rests upon a table or other support, the leaves will lie wherever they are turned, and if hung up, this position w1ll be maintained. The leaves A are sufficiently shorter than the distance between the two perforated portions so that when the upper rod 2 is inserted in a hole the leaf and rods may be lifted by pushingthis rod into its hole until the lower end can be dropped Into the hole at the bottom and rest upon the in turned su port-=5, The leaves may be thus ver rapi 1y placed or removed.

Iii. the present device I have shown an independent flexible or movable part 6 which extends alon in a line above the ends of the upper ro s 2, and forms a stop to pre- 4 isin the form of a flat table having the this portion serves asa rest for the vent their being lifted'when this part is in position. It may be maintained in this position by any suitable elastic device. .I have be operated by means of a push pin9 or' I placed; or they may be raised to allow the top pintles, and thus prevent the removal of here shown elastic arms 8 extending .down-' wardly on each side and secured to the verticalsupports 7 in such a manner that these arms normally hold the stop 6 in position above the ends of the rods 2. This stop may equivalent device by which it can bemoved rearwardly, and when so moved the pins 2 may be inserted when the leaves'are being leaves to be removed; but when the parts are in their normal position, the pins are locked and prevented from falling out.

The operation will then be as follows: When a leaf or leaves are to be removed, the stop plate '6 is moved out of line with the'upper ends of the pins or pintles at the top '0 the leaf, thus allowing the leaf to be lifted until the lower pintles are disengaged from their support, when the leaf may be readily withdrawn downwardly. hen a leaf is to be replaced, the stop 6 is moved out of line with the holes in the top plate;

the upper pintle of the leaf is inserted into its hole, and the leaf lifted far enoughto allow the lower pintle to be entered into the coresponding hole in the bottom;plate, with its end resting upon the inturned support 5, which prevents the lower edge of the leaf fromtouching the frame. By releasing the stop or locking-plate 6, this plate isallowed to move into line with the upper ends of the the leaf.

Someof the uses for this device are as follows: Directory for buildings, offices, telephone subscribers; tabulated records; pho- .tograph display rack, or album hotel regis--.

ter; and particularly it is ada ted to the display of art goods, pictures, p otographs, and for any purpose where the quick removing and replacing of the leaves allows of such quickfand easy changing of the displays, or subject'matter thereon.

Having thus described my invention, what 7 I claim and-desire to secure by Letters Patent is In a device of the bharacter described, having in combination'aframe comprising upper and lower members, said members provided with perforations and the lower back-turnededgethereof, a plate extending along above the upper ends-o the upper pintles and adapted to form a stop therefor, means whereby the plate maybe shifted out of the vertical plane of the upper pintles, elastic arms extending downwardly over each end of said plate, and vertical supporting members between the upper and lower members of the frame and to which the clastic arms are secured.

In testimony whereof have hereunto set my hand in presence of two subscribing witnesses.
